Application filed June 28. 1906. Serial No, 3233826- To all 1/271 0 m it may concern:

Be it known that I, WiLLiAM H. Pnrn, J12, a. citizen of the United States, residing at South Orange, Essex county, State of New Jersey, have invented certain new and useful .lmprowinents in O )ereting Devices for Czilcul:iti.ng-Mnchines, o which the following is n specification. v

The present invention relates to improve merits 111 machines of any character in which n rocking he-11d lever or handle is employed to actuate the ports, and is particularly adopted for use in cmineetion with calculating machines.

The object of the invention is to provide means by which it regular sctuntion of the working shaft of :iinzrchine will be secured however abrupt and irregular the operation ol the lnind lever may he.

The invention is shown in the ELOGOlH- pimving drawing as applied to n calculating machine of the character illustrated and deserihed in U. S. Patent No. 763,692, granted June 28, 1904., although, as above stated, it may he employed in'connection with. other l'crms ol hand operated nnicnines.

in the drawings, Figure l is at side elevation of n. eulculuting, nuichine illustrating one einhodiinent ol' the present inventh' in ports of the nnichimnot required to illustrate the pres nt invention being omitted, big. 12 is e.

' similar view showing the pin-ts in e ili'll'erent position; Fig. 3 is a pla n View of pzi i't of the machine: l ig'. l is :1 sectional view on theline. 4 l of Fig. 3, the ports heing in the. position shown in Fig. 2. v

Referring to the drawings, 1 designates the main or working shaft of the machine, by which the several parts of the machine, not shown, are operated, and 2 designates o eountershutt extending parallel with the main shaft and connected therewith, as will he hereinafter described. The ope ti ting handle 3 is i'nounled on a shaft 4 suitably 'ouriniled in the frame of the machine, end having an arm 5 connected by e link 6 with i uplnte-lilre arm 7 on the countersholt 2. n link 8 connects an arm 9 on the work she with :in arm 10 loosely mounted on the eountershnft, the Emil"! end of said arm 10 being; connected hr it coiled spring ll with an arm 12 rigid with'the countersluilt The niioveinent ol the main or working;

'l e utrolled ivy :i dnsmpot 3? stationniounted in. the. {mine of he unichine,

her or li'nl 6.1,

and having its plunger connected with a lever arm 14 carried by e rocking sleeve and having it second arm 14 which is connected by it link M withien arm on said working shaft.

This d esh-pot regulator insures it regular and even movement of the working shaft, end the spring 11 constituting a ielding connection between the countersheft and said working shaft provides means by which such regular movement of the working shaft will not be nll'ected by an irregular or sudden movement of the handle 3. That is, it thehiindle 3 isdrewn forward more "epidly then the working shalt 1 is permitted to move the e'llect will he to stretch the spring ll hecnuse 7.0

the arm 12, being fast on the eou ntersheft which is rigidly connected by the-link 6 with the handle shaft, will he moved at the some rate of speed. as the handle, while the arm 10,

beingloose on the eountershu-ft and linked to the working sheft,czu1 move no tester thnnthc letter shaft.

lt necessary that the handle should be retained in its forward position until the completion of the first hiilf of the movement or, the working shaft, and therefore a toggle lock provided, which, when the handle is drawn forwardly more repidly than the speed permitted the working shaft, will lock the handle and eounte-rsheit lit the limit of their forward movement until the i-orrespending movement of the working shaft has been completed. Said toggle has one ineinher connected with the arm 12 of the countershel't, and its other member 16 mounted to turn on s rodlll in the frame oi the llliLC-llll'l), 9. spring 17 being connected with the upper end of said arm 16 and acting to hold the toggle in the position shown in. Fig. 1. drawn 'torwerrhthe arm 15 0'' said toggle will be rocked downwardly from the position shown in Fig. 1 to that shown in Fi 2, end when the ports reach tl'ieposition [filOWll in the letter ligureoin which the point oi eonlee 1100131011 of the arm 12 with said toggle inern her 15 is in line. with the connection between the, toggle members and the rod 16, the parts will be locked and retained in suchposition. until rochcd hereinafter described.

A slotted connected. iLl) its rear end with the erin 10 on, the count hurt, loosely gages it PM! or stud, pro ccs ing late the toggle erm ll), one, is edit;

When the operatin handle is the member 16 of the toggle is pull of the spring 11, as hereinafter de scribed, to release the toggle look at the erases proper time.

In operating machines of the character shown in the drawing, it is essential that after a movement of the working shaft has commenced, it be completed, and therefore a full motion device is provided, consisting of a serrated member formed on the plate-like arm 7 to which the link 6 from the handle shaft is connected, and a dog pivotally mounted on the frame of the machine.

The 0 eration of the invention may be briefly d scribed as "follows: Normally the parts will occu y the positions shown in 1. If the handle be moved forwardly more rapidly than the dash-pot controller permits the working shaft to rock, the parts will be brought into the position shown in Fig. 2. That is, the spring 11- will be stretched and the toggle lock rendered operative to hold the handle and countershaft at the forward limit of their movement. As the working shaft completes the first half of its movement, the arm 10,'through the link 9 will move the bar 18 to rock the upper memher 16 of the toggle against the action of its spring 17. As soon as the members of the toggle are thus moved out of locking relation, the pull of the'spring 11 will operate to restore all of the parts to their normal position, shown in Fig. l.

The construction illustrated is very simple and compact. 'Itwill be noticed that all of the parts are arranged within the side lines of the machine, and that but a single spring, 11, is required to transmit the movements of the handle and countershaft to the main or working shaft.

By the construction described it is possible to employ a dash-pot regulator containing oil or similar fluid, the cylinder of such regulator being stationa and having the opening for the piston at its upper end.

What I claim is,-

1. The-combination of a working shaft, a countershaft, an operating handle, rigid connections between the handle shaft and counter-shaft, an arm loosely mounted on the counter-shaft, a spring connecting said arm and an arm rigid with the counter-shaft, a rigid connection between the working shaft and said loosely mounted arm on the coun ter-shaft, means for holding the handle and counter-shaft stationary until a predetermined movement of the working shaft is completed, and means actuated by theworking shaft at the completion of such movement for releasing the handle and counter-shaft.

2. The combination of a working shaft, a

counter-shaft, an o crating handle, rigid con nections between t e handle shaft and counter-shaft, connections between the countershaft and working shaft for operating the working shaft from the handle but not necesthehandls and counter-shaft, and a releasing device ada ted to be reciprocated by the and handle, substantially as described.

3. The combination of a working shaft, a counter-shaft, an operating handle rigidly connected with the counter-shaft, an arm loosely mounted. on the counter'shaft and rigidly connected with the working shaft, a. second arm rigid on the counter-shaft, a yielding connection between said arms on the counter-shaft, means for locking the handle and counter-shaft in one position until a redetermined movement of the working s raft is completed, and means actuated by the loosely supported arm on the countershaft for releasing said holding means on the completion of such movement of the working shaft.

4. The combination of a working shaft, :1 counter-shaft, an operating handle, means for o crating the working shaft from the handfd but not necessarily in unison therewith, a toggle lock having one member adapted to be moved by the handle whereby said toggle will act to hold the. handleat the limit of its movement in one direction, and an arm connected with the working shaft and adapted to engage one member of the toggle to release said to gle look when a predetermined movement of the workin shaft is com leted. 5. The combination of a working shaft, a counter-shaft, an operating handle, means for o crating the working shaft from the hand e but not necessarily in unison therewith, a toggle lock having one member adapted to be moved by the handle wherebysaid toggle will act to hold the handle at the limit of its movement in one direction, and an arm connected with the working shaft and having a slot receiv' a projection on one of the arm of the togg e lock, whereby said lock will be released on the completion of a predetermined movement of the working shaft.

6. The combination of a working shaft, a counter-shaft, an operating handle, means for o crating the working shaft from the hand e but not necessarily in unison therewith, means for looking the handle and counter-shaft in their extreme positions until a predetermined movement of the working shaft is completed, means actuated by the working shaft for releasing the handle and counter-shaft on the com letion of said movement of the working sha t, and a full motion device connected with the counter shaft, substantially as described.
